PAPER BOX.

Application filed April19, 1910. Serial N 0. 556,350.

To all whom it may cone-em:

Be it known that we, ABRAHAM L. SMITH, a citizen of the United States, residing at No. 306 Third avenue, city of New York, county of New York, and State of New -York, and ALEXANDER H. DREUX, a citizen of the United States, residing at Bloomfield, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Paper Boxes; and we do hereby declare the following to be a full, clear, and exact "description 'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to the manufacture of boxes from blanks or cartons of paper stock, such as paper board, card board, and the like, and ,particularlyto boxes intended for holding material in a more or less fine state of subdivision, and which is liable, for that reason, to sift out of the ordinary box,

such as flour, breakfast cereals, granulated.

sugar, and the like.

Generally speaking, the im rovement con sists in providing the box With an end closure having certain features of construction which efliciently serve as a safeguard against the sifting out of the contents" of the box during transportation or handling, and which may be opened out into the form of a convenientdischarge spout, after the box has been opened, and which may thereafter be closed so as to substantially exclude the external air from access to the contents or partial contents of the pened box.

In the accompanying drawings, Figure 1 represents a perspective view of a boxembodying our invention, and With the end closure partially folded, and with one of the sides partly broken away ISO as to better illustrate certain details of construction. Fig. 2 represents a plan view of the carton or blank from which the box of Fig. 1 is-made. Fig. 3 represents a partial view of a carton or blank suitable for a slightly modified form of the closure; Fig. 4 represents, in perspective, an end view'of this modified construction of box, immediately before the final step of sealing it; and Fig. 5 represents, in perspective a like view of the end of the completed box constituting said modification.

Similar letters of reference indicate similar parts throughout the several views.

Referring to the drawings, and particularly to Figs. 1 and 2 thereof. it will be noted that the box, as therein shown. consists of a folded blank, Whosemain body portion consists of subdivisions, (1, b, c. (I. together with a supplemental pasting strip a. The subdivisionsa and c constitute opposite sides of the box, when the blank is folded into its rectangular form. The subdivision a is provided with anels a constituting a continuation of said subdivision, these panels constituting ultimately the sealing flaps for the folded spout-closure. The snbdivisiornc is provided with end panels 7, and these eiid panels f are connected 'at their edges to the edges of the adjacent subdivisions 0, (Z, constituting the intermediate sides of the box, by foldable flaps made up of two sectors 9, It, which fold along a line 2'. The panels are provided with anti-sifting extensions Z, which, when the blank is. folded during the operation of closing the box,

overlap the lower margin of the end panel e,

so as to be adapted to be pasted along said lower margim Each extension Z is provided at the ends with lateral'ta-bs or projections m, which rest upon the sidefiaps when folded inward and which extend beyond the plane of the sides of: the box.

In making up the box from the blank, the main body portion is first folded intorectangular form and connected by the pasting flap e'. The end panel 6 is then turned up away from'the body of the box, and there is applied wit a coating of liquid glue, so that it is ready, toserve as a sealing fia when the foldin of the end of the box is completed. The side flaps k gand the end flap 7' are then simultaneously folded to bring them into the position shown in Fig. 1. This results in causing the extension 1 to be pasted on to the lower margin of the panel 6.. The double flaps h g are then folded in on to the flap f, and the panel e isthereupon folded down over these flaps h 9 thereby completing the sealing ofthe closures. 1n

this operationthe projections m, have pre- .vented the panel 7 from being forcedinto the interior of the box which has previously been filled. A

It will be noted that the free outer edges of the sectors 9 h of the folding'side flaps have straight portions where they merge into the flaps/a! and f, as shown in Figs. 1

other and are alined with the foldin or creasing line of the extension Z, so that 1; ese straight portions serve as a fulcrum guide when the panel 6 and the extension Z-which hasbeen pasted to it, are folded down to seal the carton. In this way the com lete closure and anti-sifting properties 0 the cartonsare assured.

The box may be conveniently opened by running a knife between the glued end panel e and the folded spout-closure, and then by running a knife between the glued surfaces of the extension Z and the said panel e, whereupon, the spout may be unfolded to advantage, that is, by swinging the sidefiaps out beyond the plane of the sides of the box, which thereby causes the panel 1 to recede sufficiently from the mouth or opening of the box to permit the insertion of the fingers. Finally, the spout can be fully opened and the panel e restored to its origina position. In this position, any part of the contents of the box may be removed by pouring through the open spout, and, thereafter, by pushing inwardly the panel f, the box may be'closed with substantial exclusion of the outer air to a degree suflicient for temporary purposes, the sideflaps rising to the position shown in -Fig. 1 and maintaining the panel f closed,

until again opened. In opening the box, as

out beyond the plane of the sides of the box causes the end panel f to jump or spring quickly in anoutward direction, to effect its opening movement. In order to provide for an especially quick and reliable opening movement of this kind, when the sideflaps are properly actuated, we find it expedient e to make the sideflaps g, h of slightlydiflerent average width, so that these fla s in conjunction with the end panel wil form a bow-like structure, one element of which is longer than the other. More particularly, the flaps g are of greater average width than the corresponding adjacent flaps h, in order thatlthe panel f and flaps 9 will normally resist being pushed into the box opening reliably in that position by .folding the side flaps inward in the position represented in j Fig. 1, wherein it is impossible for the closing panel to move outward. In the embodiment illustrated, the average width of the sector-shaped flap g is made slightly greater than that of the flap h by drawing the creasing line '5 from the center of the outer or free edge of the two flaps, considered as a unit, to a point slightly offsetfrom the apex of the angle formed by the side boundaries of the respective sidefiaps.

The form of closure illustrated in Figs. 3 t0'5 inclusive is identical with that just described, with two exceptions. In the first place, the projections or tabs at the ends of the extension Z are made, longer, as indicated at n, so that in the operation of closing the box these projections or tabs can be pasted down on the side walls of the box, as shown in Fig. 5, whereby an additional precaution against sifting is provided. In the second place, the folding or creasing line i runs to the intersection of the side boundaries of the flaps g, 71.. However, the opposite end of said line is offset from the center of the common outer or free edge of thetwo flaps, considered as a unit, so that the average width of the flap g is greater than that of the corresponding flap h, as before, with the same good results in obtaining a quick opening movement of the panel when the side flaps are moved, as previously explained.

Having thus described our invention,

what we claim is above noted, the swinging of the sideflaps In a rectangular paper box, a spout end, 7 consisting of a rectangular end panel forming a continuation of one of the sides of the box, and flaps connecting the edges of the two adjacent sidesof the box with theside .edges of said panel, said flaps being foldable inwardly on top of said panel and free to swing outwardly beyond the plane of the Isides to which they are connected, and said .fiaps consisting of two sectors of slightly different width'whereby on swinging the flaps outwardly in the act of unfolding the spout, the end panel thereof will recede from the mouthor opening of the box; substantially as described.

In testimony whereof we afi'ix our signa-- I 1 tures, in presence of two witnesses.

and assume a slightly open position, although it will be understood that when the panel fis closed by the hand it may be held ABRAHAM L. SMITH. s ALEXANDER n. DREUX. V
